Best choice

Good afternoon, We are looking for a designer to create the UI for our app. The app is under hard development but we don't have a UI creative enough person in the team. The app is really simple, we need a: Logo. Home page. Contact page. Choice page. User home page. About us( We don't know what we are writing here yet). The right person should be able to generate the templates for our app. We are looking for somebody with a deep knowledge of UI design, Usability, CSS, Twitter Bootstrap, Responsive UI, HTML but overall really CREATIVE! And attention to details! Thanks, Favalos.
